Christopher buys 1/2 pound of cheese for $3.60. How much would it cost per pound of cheese?

Answer 1

$ 7.2

Explanation:

½ pound = $3.60

1 pound = x

just cross multiply.

½x = $ 3.60

0.5x = $ 3.60

x = $3.60/0.5

x = $7.2

Answer 2

`\huge\boxed{\sf \$ 7.20}`

Explanation:

Given that,

1/2 pound of cheese = $3.60

Using unitary method.

Multiply 2 to both sides

1 pound of cheese = $3.60 × 2

1 pound of cheese = $7.20

`\rule[225]{225}{2}`
